1.5.24: rxvt or console fail to shutdown due to ssh -f still running despite setsid()

I'm not running ssh as a daemon. What I do in order to ssh to another
computer from any other shell is to keep one shell open all the time
running the agent. This is accomplished via the startssh function. In
the function I alias exit to call the stopssh function assuming of
course that this shell is the last to close. My rxvt closes just fine
this way. You only want to startssh one time. The alias ssh then
sources in the current agent information and calls the real ssh.
KSAGENT="`type ssh-agent 2>/dev/null|sed 's/.* is //'`"
if [ -n "$KSAGENT" ]; then
ssh-agent |sed '/echo Agent pid/d' > $HOME/.ssh/current_agent
PROMPT_COMMAND='echo -n -e "\033]0;SSH-AGENT Started! $PWD\007"'
eval `ssh-agent -k`
alias ssh="source $HOME/.ssh/current_agent;ssh"
